Resize an image to 1200 × 630

1200 by 630 is the Open Graph image, the picture that appears when your link is shared on Facebook, LinkedIn, Slack or almost anywhere else. Getting it wrong is why shared links sometimes show a cropped or blank preview. Drop a photo in and it comes out at exactly 1200 by 630, cropped to fit rather than squashed. Nothing is uploaded.

What 1200 by 630 actually weighs in each format

We put the same 600 by 600 portrait through this tool at 1200 by 630 and weighed all three outputs. JPG and WEBP at quality 90.

825.1 KBas PNG
73.6 KBas JPG at 90
38.8 KBas WEBP at 90
11xPNG vs JPG

PNG is lossless, which is why it is 11 times heavier than JPG here and 21 times heavier than WEBP. Use PNG only when you need transparency or perfectly crisp text and lines. For a photograph at 1200 by 630, WEBP at quality 90 came out at 38.8 KB and is almost always the right answer.

Aspect ratio

1200 by 630 is 40:21

1200 by 630 reduces to 40:21, a ratio of 1.905 to 1. Most phone photos are 4:3 or 3:4, which is 1.333 to 1, so unless your source already matches 40:21 the shape has to change on the way in.

That is what the Fit control is for. Crop to fill scales your photo until it covers the whole frame and trims the overflow, so nothing is distorted but something is lost. Fit inside scales until the whole photo is visible and pads the gap with a colour, so nothing is lost but bars appear. Stretch forces the photo into the frame and is the only option that distorts faces.

Crop to fill is the default here because a distorted face is much more obvious than a cropped edge, and because most systems asking for a fixed size expect the frame to be filled. Switch to Fit inside when the whole image genuinely has to stay visible, such as a logo or a diagram.

The 1.91:1 ratio is what the Open Graph spec settled on. Text near the edges of this shape is often clipped by the platform preview.

Honest limits

What this tool will not do

It will not invent detail

If your original is smaller than 1200 by 630, this tool will still produce a 1200 by 630 file, but the extra pixels are interpolated rather than real. Enlarging interpolates, it does not add information. If you need a genuinely larger image, start from a larger original or try the image upscaler, which is honest about the same limit.

It will not let you choose what gets cropped

Crop to fill takes the centre of your photo. If the part that matters is off to one side, crop it deliberately first with the image crop tool, then bring the result here.

It will not hit a target file size

This tool fixes the dimensions, not the bytes. To land under a specific limit such as 100 KB, send the result through the image compressor, which searches for the quality that meets your target.

FAQ

Frequently asked questions

How do I resize an image to 1200 by 630?

Drop your photo into the box above. The tool is fixed to 1200 by 630, so the output is always exactly that, and it downloads as soon as you click. Nothing is uploaded to a server, the resize happens in your browser.

Will resizing to 1200 by 630 distort my photo?

Not with the default setting. Crop to fill scales your photo until it covers the 1200 by 630 frame and trims whatever hangs over the edge, so proportions are preserved. Only the Stretch option distorts, and it is there because a few systems genuinely want the whole image squeezed in regardless.

What file size should I expect at 1200 by 630?

It depends entirely on format. Our 600 by 600 test portrait came out at 825.1 KB as PNG, 73.6 KB as JPG at quality 90, and 38.8 KB as WEBP at quality 90. Detailed photographs will be heavier than flat graphics at the same dimensions.

Which format should I choose for 1200 by 630?

WEBP if the destination accepts it, since it was 53% the size of JPG in our test at the same quality. JPG if you need maximum compatibility. PNG only for transparency or crisp text, because at this size it was 11 times heavier than JPG.

What if my image is smaller than the target?

The tool will still output 1200 by 630, but it cannot invent detail that was never captured. Upscaling interpolates between existing pixels, which softens edges. Start from the largest original you have.

Is my image uploaded to a server?

No. The file is read by your browser, drawn onto a canvas and encoded there. You can confirm it by opening your network tab while you use the tool, or by disconnecting from the internet and resizing anyway.
